Not true.Goku was stated as faster than lightning as a child back in the Dragon Ball Manga, during IIRC his training with Kami.
Lightning travels up to half the speed of light. And Goku has gotten literally millions of times more powerful since then.
He also has a light speed reaction feat when he moved and put on Roshi's sunglasses before the light from Tien's Solar Flare ever reached his eyes. Also back during Dragonball.
As for Superman? Jesus christ peeps. The guy does insanely complex things in short order. Like building an entire cities in seconds. Fighting at superspeed is an afterthought in comparison.
As for the solar flare thing prove the solar flare goes light speed.And even then did he grab for them after Tien said it?
